12 Claims.

in structure, which may be cheaply and economically manufactured, which may be quickly and conveniently installed, and which comprises support-engaging fixtures and insulator-supporting brackets uniquely constructed for rack enlargement or for selective disposition of the brackets 15' for facile meeting practically all pole or line requirements.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combinations of parts presently described and pointed out in the claims.

In the accompanying drawings (2 sheets), Figures 1, 2, and 3, are perspective views of, re-

spectively, the co-operable parts or members,

namely, attachment-fixture, insulator-bracket or hanger, and insulation wire-engaging spool, of an so-called secondary rack embodying my present invention;

Figure 4 illustrates in longitudinal section a pair of the racks in associated or gang relation; Figure 5 is a fragmentary front elevational view of the ganged or associated racks of Figure 4;

Figures 6, 7, and 8 are transverse sectional views of the rack taken approximately along the lines 6-6, 'I'I, and 8-8, respectively, Figure 4; and

Figure 9 illustrates in side elevation the manner of attachment of an assembled insulator and hanger directly to a wall, the attachment fixture 40 being omitted.

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of my invention, the rack includes an oblong-rectangular fixture or attachme-nt base A constructed preferably as a unitary casting from malleable iron or other suitable metallic material and comprising preferably integrally a pair of approximately parallel longitudinal or side walls I connected or joined at their one or upper end by a transverse wall or bar 2 having, reference being made to Figures 1 and 4, a lower face 3 presented obliquely inwardly and downwardly intermediate the walls I. At their lower end, the walls I are formed with obliquely downwardly and inwardly presented registering extensions 4 providing a notch, as at a, therebetween and the lower or outer end face of the walls I, the extensions 4 being connected or joined by a second transverse wall or bar 5 having an obliquely inwardly and downwardly outer face 6 and provided in its top margin with a cutout or notch, as at b, as best seen in Figure l and all for purposes presently appearing.

Suitably spaced at their one or upper end from the upper end-wall 2, so as to provide an opening, as at c, at the upper end of the base A, are so-called arcuate heads 1, which are presented inwardly from and with respect to the upper margins of, and which extend longitudinally of the fixture for some distance along, the walls I, and joining the beads I transversely of the fixture, is a top wall or web 8 having in suitably spaced relation longitudinally of the fixture an annular opening or aperture, as at d, and an elliptical opening or aperture, as at e, and provided centrally at its lower margin with a downwardly presented bendable or malleable tongue 9, the channels 1 of the beads 1 providing concealed ways or tracks adjacent the opposite inner faces of the walls I, all as best seen in Figures 1 and 8 and for purposes presently appearing.

Throughout the remainder of their length from approximately the transverse plane of the lower end of the tongue 9, the walls I are extended forwardly, as at I and such extensions I a are laterally formed upon their free margins with pairs or sets of opposed tongues Ill-I0 and IIII suitably disposed in spaced tandem relation longitudinally of the fixture, the tongues of each pair being suitably spaced one from the other transversely of the fixture in the provision of aligning wedge-shaped ways, as best seen in Figure 1 and for purposes presently appearing. Preferably for symmetry and strength, the pairs or sets of tongues I D, II, are joined longitudinally of the fixture by intermediate front wall flanges I2 presented laterally in opposed relation from the wall-extensions I at their upper margin, and the tongues II) are preferably re-enforced or strengthened by triangular webs I3 disposed between the under faces of the tongues III and the inner faces of the walls I, as best seen in Figure 1.

Extending longitudinally of the fixture from the base of the oblique face 6 of the lower end wall 5 and provided on its upper face and marginally from the side-wall extensions 4 with par-' allel ribs I4, is a suitably elongated tongue in the form of a web I 5 disposed in such plane for endthe somewhat angular notch or recess a, as

shown.

Along their rearwardly presented longitudinal margins, the side walls 1 are provided with narrow lateral flanges I! and a pair of outwardly presented apertured ears 18 preferably suitably continuously beveled on their under face for snugly fitting upon the arcuate surface of, and attachment to, a telephone post or the like P, as best seen in Figures 4 and 5. As shown particularly in Figure 5, the ears [8 accommodate suitable bolts, as I8 for convenient attachment of the fixture A to a supporting structure, as, for instance, the post P, the connection of the fixture A upon the post being supplemented by an additional bolt lB preferably projected into the post through the opening e, substantially as shown.

Co-operable with the fixture A, is a clevisshaped hanger or bracket B preferably in the form of a U-shaped malleable casting integrally including a bight l9 and opposed parallel legs 2!), 2!, preferably annularly enlarged at their free outer ends in the provision of insulatorreceiving enlargements or so-called eyes 22, 23, having registering apertures 24.

Upon its outer or rearwardly presented face, the bight I9 is suitably thickened in the provision of a central bossor lug joined by diametrally opposite fillets or necks ZBto enlargements 21, 28, marginally undercut in theprovision of wedge-shaped grooves or ways 29, 30, complementary in shape to, and for hanger-engagement with, the tongues In, H, of the fixture A, as best seen in Figures ,4 and 5.

Adjacent the bight l9 and on its outer face, the clevis-leg 2! is also provided with alike enlargement3l, and the enlargement 3| and the eye 23 are similarly marginally undercut in the provision of wedge-shaped grooves 32, 33, for also selectively accommodating, and for engagement with, the fixture tongues 10, H, as presently more fully appears.

Upon their inner face, the hanger-legs 20,

2|, are centrally provided longitudinally with strengthening ribs 34, and joining the respective, eyes 22, 23,,and the respective way-rproviding enlargements 21, 28, 31, upon the outer face of the, hanger B, are preferably additional re-enforcing ribs 35, all as best seen in Figure 2 and forrpurposes presently more fullyappearing.

Sized for fitting snugl intermediate the opposed faces of the clevis eyes 22, 23, is a spoolshapedinsulator C constructed preferably of porcelain or other suitable dielectric materialand provided with an axial bore, as at 36,. for accommodating a supporting shaft 31 for projection endwise. into the registering apertures 24,. and fittinglengthwise in slots or recesses, as at. 38, provided in theinner face of the hanger-eye 22 and engaging the.shaft.31, is a locking-pin. 39. The fixture A and. insulator-equipped hanger or bracket B are. thus co-operatively.uniquely formed for selective detachable engagement, the bracket B either at its bight l9 or at its leg 2| being engageable with the fixture tongues [0, II, with the insulator C correspondingly disposed, as may best meet the requirements of the line or installation, either in parallel or rightangular relation to the fixture A, as shown in Figure 4, the tongues 10, I I, being engaged either in the ways 29, 30, or 32, 33, as the case may be. In either arrangement, the arcuate portion 35 of an abutting outer rib 35 will be snugly accommodated by the recess or notch 11 in the fixture wall 5, and when so selectively engaged with the fixture A, the fixture-tongue 9 may be bent outwardly by means of a screw driver or other suitable instrument into endwise abutting engagement with the then outwardly presented face of either the enlargement 21 or the eye 23, as the case may be, for preventing accidental displacement of the bracket B, all as best seen in Figures 4 and 6.

The boss or lug 25 and bight l9 are preferably provided with a continuous opening, as at 40, and hence, I may add that, to meet line or installation requirements, the insulator-equipped clevis or bracket B may be secured directly upon a post, wall, or the like by means of a conventional lag-bolt 4| projected thereinto through such opening 40, as best seen in Figure 9.

The rack eficiently fulfills and performs in every respect the objects stated and all its intended functions, and it should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the rack may be made and substituted for those herein shown and described without departing from the nature and principle of my invention,
